The cement sector is at odds with the principles of the circular economy
False. Every year the Italian cement sector recovers over 7% of its raw material requirements from other industrial processes, for a total of about 1.8 million tons of natural raw material replaced.
These recovered materials take the place of natural raw materials that are introduced into the grinding process to obtain the raw meal used to produce the clinker.
Furthermore, the UNI EN 197/1 standard permits the reduction of the clinker content per unit of cement, allowing the use of raw materials derived from other industrial processes. To date, the substitution of material that replaces clinker per unit of cement is around 25%, and the entire supply chain is working to increase this percentage every day.
Moreover, more than 350,000 tons of waste are kept out of landfills and incinerators and used instead as alternative fuels in kilns for the production of clinker, with a caloric substitution of about 17%, and more than 250,000 tons of CO2 are not emitted in the atmosphere thanks to the fact that these fuels contain biomass.
The action and interest of the sector in extending the use of recovered raw materials is therefore constant, in order to achieve European objectives and actively contribute to the transition to an increasingly circular economy.
